1.2 REACTlVlTY BALANCE J. R. Engel The extended periods of full-power reactor operation in runs 11 and 12 have provided the most severe tests to date of the on-line reactivity balance calculation. Runs 11 and 12 increased the integrated power by 16,200 and 7650 Mwhr, respectively, to a total of 40,307 Mwhr. In addition to the usual calculations of power- and timedependent factors, calculations were required in each of these runs to compensate for 235U additions that were made with the reactor at full power. The overall performance of the calculation was highly satisfactory, and no anomalous reactor behavior was indicated at any time. However, some additional calculation modifications were required to eliminate errors that developed. 19 Fig. 1.5. Residual Reactivity During MSRE Run 11. Balances at Power Figures 1.5 and 1.6 summarize the results of the on-line calculations during this report period. These results are reproduced exactly as they were generated, with no corrections for computer- induced errors. For legibility, only about 2% of the data points are shown, but each plotted point is the result of an individual calculation. Thus the scatter in the plotted points is an indication of the precision of the calculation. The points at which changes were made to correct errors are indicated by notes. Except for one negative excursion caused by circulating voids immediately after a power shut- down in run 11 (Fig. l.S), all the calculated values of residual reactivity were between -0.03 and t 0.10% 8k/k. An apparent gradual decline in
